I have a 2014 Mo SL FWD that was throwing a couple of MAF Sensor codes (0101, 0103, 0113) and 1 CVT code (0746). The CVT would judder (Nissan's word for it) which I'd describe as a slip and shudder when stating out on an incline and accelerating. The Mo went into limp mode at one point and I parked it until I could work on it. After much research on Mo forums, and some discovery when I replace the spark plugs, I seem to have fixed all issues. For MAF, I found the the ribbed hose from air filter cover to the throttle body had separated in a couple of places (this was the source of the MAF codes). I cleaned the MAF sensor and the throttle body and replaced the ribbed hose assembly (I didn't unhook the electrical harness from the throttle body because then I would of had to do idle relearn - which is tedious). I then drained 5.5 quarts of CVT fluid and add same amount of Ns-3 CVT fluid. Drove the car about 10 miles and as I pulled into my garage (on an incline) got the Judder - arggg!!! This is not a mild thing. It is a violent shudder and accompanied by loss of power to CVT - car doesn't move forward. I decided to drive the Mo gently (no rapid accelerations from start on an incline) for another 90 miles. Theory here is that code P0746 is for CVT Pressure Control Solenoid (PCS) dirty/clogged/stuck (in general) - likely cause being dirty CVT fluid. Additional driving was to get good circulation of CVT fluid and hopefully clear the PCS. It worked. Judder gone! All codes cleared!! I bought a case of the Ns-3 fluid and plan to drain another 5.5 quarts and refill to get the concentration of fresh fluid higher in the CVT. This beats CVT replacement which is where I thought this was going. I found 1 post somewhere discussing a relationship to MAF sensor and CVT issues, so don't know how much of a contributor that was to my CVT issue. I suspect the fluid was likely culprit.... Also changed the plugs and pcv valve as part of this round of maintenance. Hope someone finds this post useful.
